This paper establishes Professional Dialogue as a distinct research methodology, developed through Peter Garrett's decades of practice in prisons, corporations, and systemic change work. The centrepiece is a case study from a juvenile detention facility where official data showed minimal sexual harassment, but dialogic inquiry revealed a pervasive, institutionalised problem that staff had normalised. The methodology differs from traditional research in key ways: findings are shared transparently with each stakeholder group as they emerge; the researcher moves through organisational layers building collective understanding; and the process generates ownership of both the problem and proposed solutions. Garrett introduces the Implicate Change Model, a seven-phase sequence for bringing coherent change to fragmented systems. The paper directly challenges researchers to consider how their methods may inadvertently obscure the truths that transparent, dialogic approaches can surface when conducted with skill.
